Electrophoretic coating is a pioneering technology that immerses the object to be painted in a water-soluble paint bath, designating it as the anode (anodic electrophoresis). A corresponding cathode is set up, and a direct current is applied. This electric current ensures that the paint is uniformly and meticulously coated on the object, leveraging both physical and chemical effects of the current.
The meticulous process flow of electrophoretic coating on general metal surfaces encompasses: Pre-cleaning → On-line → Oil removal → Washing → Rust removal → Washing → Neutralization → Washing → Phosphating → Washing → Passivation → Electrophoretic coating → Tank cleaning → Ultra-filtration → Drying → Off-line.
The electrophoretic coating process generally comprises four simultaneous and intricate stages.
1. Electrophoresis: Under the influence of a direct current electric field, the positively and negatively charged colloidal particles migrate towards the negative and positive electrodes respectively, a process also referred to as swimming.
2. Electrolysis: Redox reactions are conducted at the electrodes, resulting in oxidation at one electrode and reduction at the other, forming distinct phenomena on each electrode.
3. Electrodeposition: Driven by electrophoresis, charged colloidal particles move towards the anode, release electrons at the template surface, leading to the deposition of paint in an insoluble state, culminating in the formation of a paint film.
4. Electroosmosis: Within the electric field, the solid phase remains static while the liquid phase moves. This movement expels water from the paint film, resulting in a dense paint layer with high resistance and minimal water content, even impermeable to current.
5. Iron Red Epoxy Electrophoresis Paint Example: The electrophoretic paint system modified with epoxy resin, butanol, ethanol amine, talc, and iron red substances, when mixed with distilled water and subjected to a DC electric field, splits into positively charged cations and negatively charged anions, initiating a series of complex physical, chemical, colloidal, and electrochemical transformations.
Electrophoretic coating boasts a swift construction speed, enabling mechanized and automatic continuous operations. This significantly reduces labor intensity while ensuring a uniform, smooth, and strong paint film, even on difficult-to-coat parts such as welding seams of fascia plates, unattainable by traditional methods.
The paint utilization rate in electrophoretic coating is impressively high, ranging from 90%-95%. Additionally, the use of water as a solvent offers numerous benefits such as non-combustibility, non-toxicity, and ease of operation.
The paint film dried after electrophoresis exhibits exceptional adhesion, coupled with superior rust resistance, corrosion resistance, and weather resistance, outperforming ordinary paints and conventional application methods.
